“…Se consideró que la extracción de residuos forestales debe hacerse casi inmediatamente después de la extracción de productos primarios. Tomando como base estudios similares (Perlack et al, 2005;Perez-Verdin et al, 2009), se calculó la densidad de caminos a nivel municipio y se estableció un porcentaje de estimación de biomasa basado en su accesibilidad como sigue: 0,7 si la densidad de caminos (km km -2 ) es mayor a 0,24; 0,65 si la densidad varía entre 0,16 y 0,24 y 0,6 si la densidad es menor a 0,16. Los coeficientes de accesibilidad se multiplicaron por la biomasa residual después de la compensación por perdida de nutrientes en el suelo.…”

ResumenLa biomasa forestal es una alternativa ecológica y económicamente viable para la generación de bioetanol debido a que su fuente es abundante, renovable y contribuye a la reducción de gases efecto invernadero. En este estudio, se propone y analiza una metodología para la estimación de la disponibilidad y costos de producción del uso potencial de la biomasa forestal como materia prima para la producción de bioetanol en bosques de pinos del estado de Durango, México. Se usó información del Inventario Forestal Periódico, programas de manejo forestal y datos de empresas de aserraderos e industriales forestales para estimar la biomasa forestal que incluye los restos de aprovechamientos forestales (puntas, ramas) y desperdicios industriales (aserrín, costeras). Se utilizaron simulaciones Monte Carlo para estimar costos de producción de la recolección, extracción y transporte de la biomasa a centros de transformación. Los resultados indican que alrededor de 322.000 toneladas pueden utilizarse para la producción de 38 millones de litros de etanol por año. Las simulaciones Monte Carlo indican que el costo promedio de residuos forestales es de US $23,8 por tonelada (US $0,20 L -1 etanol) mientras que el de residuos industriales es de US $22,6 por tonelada (US $0,19 L -1 etanol). Los factores más importantes en el análi-sis de sensibilidad fueron el costo pagado a dueños del material, eficiencia tecnológica y distancia de transporte. En el corto plazo, el uso de la biomasa forestal para la generación de biocombustibles tiene varios retos entre los que se encuentran los costos de transporte y la competencia generada por industrias similares como pulpa, papel y tableros aglomerados. Como alternativa se encuentra el desarrollo de biorefinerías integradoras y el uso de medios de transporte más eficientes.Palabras clave: biocombustibles; costos de producción; Durango, México; residuos forestales; residuos industriales; simulaciones Monte Carlo. Abstract Availability and production costs of forest biomass as a feedstock for bioethanol productionForest biomass is a viable alternative to produce ethanol because is abundant, clean, renewable, and can help mitigate greenhouse gas emissions. In this study, a methodology to estimate availability and production costs of forest biomass in forest pines of the state of Durango, Mexico is presented. Forest periodic inventory, forest management plans, and sawmill information were used to estimate forest residues and mill residues, respectively. Since a market for bioethanol from forest biomass is still not well defined, Monte Carlo simulations were conducted to estimate procurement, transportation, and stumpage costs. Results show that about 322,000 tons can be used to produce up to 38 million of liters of ethanol per year. Of that amount, 66% is forest residues and the rest mill residues. Monte Carlo simulations indicated that the average cost of forest residues is US $23.8 per metric ton (US $0.20 L -1 ethanol) while the cost for mill residues is US $22.6 per metric ton (US $0.19 L ...

“…A plethora of literature exists on the economic availability of biomass [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. A recent report by the US Department of Agriculture and Department of Energy concluded that 1.3 billion tons of biomass are available annually for energy production [18,19].…”

A challenge in the development of renewable energy is the ability to spatially assess the risk of feedstock supply to conversion facilities. Policy makers and investors need improved methods to identify the interactions associated with landscape features, socioeconomic conditions, and ownership patterns, and the influence these variables have on the geographic location of potential conversion facilities. This study estimated opportunity zones for woody cellulosic feedstocks based on landscape suitability and market competition for the resource. The study covered 13 Southern States which was a segment of a broader study that covered 33 Eastern United States which also included agricultural biomass. All spatial data were organized at the 5-digit zip code tabulation area (ZCTA). A landscape index was developed using factors such as forest land cover area, net forest growth, ownership type, population density, median family income, and farm income. A competition index was developed based on the annual growth-toremoval ratio and capacities of existing woody cellulosic conversion facilities. Combining the indices resulted in the identification of 592 ZCTAs that were considered highly desirable zones for woody cellulosic conversion facilities. These highly desirable zones were located in Central Mississippi, Northern Arkansas, South central Alabama, Southwest Georgia, Southeast Oklahoma, Southwest Kentucky, and Northwest Tennessee.

“…The data were part of an inventory conducted by Periz-Verdin [4] who drew from two main sources, namely, the Mississippi Institute for Forestry Inventory (MIFI) satellite imagery-based data, and Forestry Inventory Analysis (FIA) Timber Products Output database (TPO) forest inventory data. The quantity of logging residues was based on the FIA-TPO forest inventory data as reported by the Southern Research Station.…”

“…It covers 18 million acres or 62% of the total land area in Mississippi. In Mississippi, about four million dry tons of woody biomass is available for energy production, distributed into four major types namely, logging residues (70%), small diameter trees (20%), urban wastes (7%), and mill residues (3%) [4]. Logging residues represent a significant feedstock that can be utilized for energy production, and it is less expensive than small diameter trees.…”

Combined Heat and Power (CHP) production using renewable energy sources is gaining importance because of its flexibility and high-energy efficiency. Biomass materials, such as corn stover and forestry residues, are potential sources for renewable energy for CHP production. In Mississippi, approximately 4.0 MT dry tons of woody biomass is available annually for energy production. In this study, we collected and analyzed 10 years of corn stover data (2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010) and three years of forest logging residue data (1995, 1999, and 2002) in each county in Mississippi to determine the potential of these feed stocks for sustainable CHP energy production. We identified six counties, namely Amite, Copiah, Clarke, Wayne, Wilkinson and Rankin, that have forest logging residue feedstocks to sustain a CHP facility with a range of capacity between 8.0 and 9.8 MW. Using corn stover alone, Yazoo and Washington counties can produce 13.4 MW and 13.5 MW of energy, respectively. Considering both feedstocks and based on a conservative amount of 30% available forest logging residue and 33% corn stover, we found that 20 counties have adequate supply for a CHP facility with a capacity of 8.3 MW to 19.6 MW.
